Energy Harvesting Module and Low Power Rectifier Circuit
RADIO frequency (RF) energy harvesting has garnered much interest in recent years as our lives have become more connected. Whether it be smart homes, industry 4.0, wearables or sport-tech; objects which were once inanimate are brought to life with electronics such as sensors, and low-power transceivers. This evolution of ‘things’ is commonly referred to as […] Read More >
Text-Guided Real-World Image Restoration
Capturing images in limited conditions (such as low-light, high dynamic range, etc.) is hard and the resulting images are not good. Since the camera is limited in such scenarios, capturing such scenes becomes difficult. Using a novel image processing method with artificial intelligence (AI) technology the user can talk to the camera and describe the […] Read More >
Using Eye-Tracking in VR to Identify Subject Preferences to Optimize Personalization
The implementation of virtual reality (VR) has been spreading in many research fields and healthcare applications. In order to better personalize the presented content, there is a need to identify the subjective experience at each time point. Previous studies with eye-tracking (ET) have demonstrated its links to preferences; therefore, collecting ET data during VR experiences […] Read More >
Novel gas sensors with enhanced selectivity based on integrated magnetic and conductometric measurements
Reliable detection of hazardous gases has become a key issue due to the more stringent environmental and safety regulations worldwide. Solid-state conductometric gas sensors present a high potential for applications where the use of conventional analytical systems such as gas chromatography or optical detection is prohibitively expensive or impossible. The operation of such sensors […] Read More >
Image Processing – Non-Local Image Dehazing
Prof. Shai Avidan Tel Aviv University, School of Electrical EngineeringHaze limits visibility and reduces image contrast in outdoor images. The degradation is different for every pixel and depends on the distance of the scene point from the camera. This dependency is expressed in the transmission coefficients, that control the scene attenuation and amount of haze […] Read More >
Online Training of Stereo Self-Calibration usingMonocular Depth Estimation
Stereo imaging is the most common passive method for producing reliable depth maps. Calibration is a crucial step for every stereo-based system, and despite all the advancements in the field, most calibrations are still done by the same tedious method using a checkerboard target. Monocular-based depth estimation methods do not require extrinsic calibration but generally […] Read More >
Anomaly Detection in Video
We propose a new method for anomaly detection of human actions. Our method works directly on human pose graphs that can be computed from an input video sequence. This makes the analysis independent of nuisance parameters such as viewpoint or illumination. We map these graphs to a latent space and cluster them. Each action is […] Read More >
Novel Elastic Flapping-wings for Micro Air Vehicles
The technologyFlexible, 3D printed insect-inspired wings that elastically deform during flapping to improve flight performance and efficiency. The deformations are inspired by wings of beetles, adapted for different flight styles 1,2. The passive elastic deformations that the wings undergo during flapping are engineered at the fabrication stage to tailor the wing for specific flight missions […] Read More >
Partially coherent radar for car applications
Many different approaches for mapping nearby moving objects are under fast development nowadays due to a number of highly important emerging applications, including autonomous cars and many others. The majority of existent proposals for solving the problem are based on optical imaging with subsequent post processing. While this concept already delivered impressive working prototypes (e.g. […] Read More >
Passive communications with time-varying metamaterials
The coming years will see a revolution by connecting everything to anyone, and RFID and similar technologies, will lead this 300B$ USD industry and 50B connected devices. Examining existing RFID standards suggests that the leading standard, called EPC Gen 2, is a standard in the 900MHz frequency which allows hundreds of tags to be read […] Read More >
